C++
// templateInstantiationInvalid.cpp
#include <iostream>
#include <vector>
template <int Nom, int Denom>
class Rational{
public:
    int getFloor(){
        return Nom / Denom; 
    }
};
    
// template int Rational<5, 0>::getFloor();
int main(){
  std::cout << std::endl;
  
  Rational<5, 3> rat1;
  std::cout << "rat1.getFloor(): " << rat1.getFloor() << std::endl;
  Rational<5, 0> rat2;
  // std::cout << "rat2.getFloor(): " << rat2.getFloor() << std::endl;
  
  std::cout << std::endl;
  
}
